Matteo Marongiu Porcu

Senior Reservoir and Completions Engineer

Matteo Marongiu-Porcu is a Senior Reservoir and Completions Engineer at ResFrac with almost twenty-five years of international experience spanning North America, South America, Europe, and North Africa. Passionate about integrating technical precision with operational strategy to drive performance and mitigate risk, Matteo has built his career developing and deploying advanced solutions to optimize production in both conventional and unconventional reservoirs.

Matteo’s expertise includes completions engineering, hydraulic fracturing, matrix stimulation, reservoir diagnostics, geomechanics, and numerical modeling workflows. Prior to his work at ResFrac, Matteo started his career as a completions and stimulation engineer at ENI E&P and Economides Consultants, and has held technical advisory roles at Schlumberger, Chesapeake Energy, NexTier, and Chevron, with a proven track record across 100+ projects in diverse geological settings.

Matteo held adjunct-faculty appointments at the University of Houston’s Petroleum Engineering Department from 2014 to 2022, where he taught two graduate-level courses on production optimization, reservoir testing, and stimulation.

Matteo holds a PhD in Petroleum Engineering from Texas A&M University, an MS in Petroleum Engineering from the University of Houston, and a five-year diploma in Chemical Engineering from Politecnico di Milano.

In his free time, Matteo enjoys watching movies with his wife, open water swimming, riding his motorcycle, collecting vintage comic books, and racing slot cars.

The influence of well configuration on water loss in Enhanced Geothermal Systems

Recently, ‘water loss’ has been a hot topic of discussion for EGS. Fervo reported that they have been producing only 70% of the fluid volumes that they have been injecting at their Project Red. The FORGE project reported a roughly 10% water loss rate. Because projects will have finite water rights, these results have led to concern that growth of EGS will be limited by excessive water consumption. This is a valid concern, and water availability is a legitimate factor in site-selection and project engineering. However, I believe that the problem has been overstated.

2026 ResFrac Annual Symposium Recap

On June 25, 2026, we got the ResFrac community together both in-person at the ExxonMobil campus in Spring, Texas, and virtually around the globe for our Annual Symposium. With our community growing as fast as it is, the energy in the room was absolutely buzzing. We had a jam-packed day of operator case studies, deep-dive technical sessions, and some incredible geomechanical insights from industry legends.

FracTest – An Online Tool for DFIT Interpretation

This week, we are releasing FracTest, a web-based application for interpretation of diagnostic fracture injection tests (DFITs). FracTest is available at resapps.resfrac.com, alongside our other two ResApps, StageOpt and IntTest. DFITs are small-volume fracture injection tests used to estimate stress, pore pressure, and permeability. These quantities form the foundation of the fracture and reservoir engineering work that we do in ResFrac, and so we view DFIT interpretation as one of the most important parts of our workflow.
